Child-proof package for pharmaceutical products

ABSTRACT

A form of child-proof package for tablets and similar pharmaceutical products, features a blister pack with at least one blister which is closed off by a push-through type foil lid, the blister serving the purpose of accommodating the tablets. For the purpose of removing the tablets, the push-through type foil lid of the blister pack lies against a wall part and with respect to that can be displaced by sliding from a closed position to an open position so that, when in the open position, the blister with the tablets lie in line with openings in the wall part and the tablets can be pushed through the openings The blister pack is arranged between a rear wall part and a front part, and the wall part with the openings lies between the rear wall part and the foil lid. The blisters can be displaced by sliding from the closed position to the open position into opening slits and the openings in the inner wall part are covered over by a tear-off strip which is arranged in the rear wall part and can be separated from it along a line of weakness forming a longitudinal slit.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation-in-part of our prior patentapplication Ser. No. 09/986,525 filed Nov. 9, 2001 (pending).

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to child-proof packages forpharmaceutical products in the form of solid, pulverized or liquid topasty doses as e.g. tablets, capsules, ampoules or dragées, featuring ablister pack with at least one blister which is closed off by apush-through type foil lid, the blister serving the purpose ofaccommodating the pharmaceutical product(s). The packaging is such that,for the purpose of removing the pharmaceutical product, the push-throughtype foil lid of the blister pack lies against a wall part whichprotects the foil lid and with respect to which it the blister canoptionally be displaced by sliding from a closed position to an openposition so that, when in the open position, the blister with thepharmaceutical product lie in line with openings in the wall part andthe pharmaceutical product can be pushed through the openings.

[0004] 2. Background Art

[0005] The danger of uncontrolled consumption of medicaments isundisputed; in particular, small children are especially exposed to thispotential danger in the form of medicaments that have been left lyingaround.

[0006] The most common form of packaging for tablets and similarpharmaceutical products is that of blister packs. Widely known inparticular is the so called push-through pack which is such that thetablet is pressed out of a cup in the base part of the pack (theso-called “blister”) and through a foil lid. Another known form ofblister pack is such that a foil lid is removed by peeling. Otherblister packs feature a notch as an aid to tearing.

[0007] The present day possibilities for increasing child safety inconnection with blister packs mainly involve increasing the difficultyof opening by means of measures that require greater strength, e.g.thicker push-through films, greater force of adhesion of peeling films,or higher force of friction in the case of tearing notches.

[0008] Forms of packaging which can be opened only by applying greaterforce are indeed more child proof, but can present problems for seniorcitizens.

[0009] Known from International patent application WO-A-96/03329 is achild-proof form of packaging in which the lid film of the blister packis covered by a rear wall part. Integrated into this rear wall part aretearing strips that can be removed along a line of weakness. In order tobe able to push the tablet out of the blister through the lid film, thetearing strips have to be removed first.

[0010] A child-proof packaging of the kind mentioned at the start ofthis specification has been disclosed in the U.S. Pat. No. 5,150,793which issued on Sep. 29, 1992 to PCI/Delvco Inc.

SUMMARY OF THE INVENTION

[0011] An object of the present invention is to provide a form ofpackaging of the kind mentioned at the start of this specification suchthat a combination capability is necessary to open it or a simultaneousor complex sequence of movements must be carried out.

[0012] According to one aspect of the present invention, there isprovided a child-proof package for pharmaceutical product(s), comprisinga blister pack with at least one blister which is closed off by apush-through type foil lid, the blister serving the purpose ofaccommodating the pharmaceutical product(s), the packaging being suchthat, for the purpose of removing the pharmaceutical product(s), thepush-through type foil lid of the blister pack lies against a coveringwall part with respect to which the blister pack can be displaced bysliding from a closed position to an open position so that, when in theopen position, the blister with the pharmaceutical product(s) lies inline with openings in the covering wall part and the pharmaceuticalproduct, can be pushed through the openings, wherein the blister pack isarranged between a rear wall part and a front part and the covering wallpart with the openings is an inner wall part lying between the rear wallpart and the foil lid, whereby the blisters can be displaced by slidingfrom the closed position to the open position into opening slits and theopenings in the inner wall part are covered over by a tear-off stripwhich is arranged in the rear wall part and can be separated from italong a line of weakness thus forming a longitudinal slit.

[0013] According to another aspect of the invention, there is provided achild-proof package for tablets and similar pharmaceutical products,comprising a blister pack with at least one blister which is closed offby a push-through type foil lid, the blister serving the purpose ofaccommodating the pharmaceutical product(s), the packaging being suchthat, for the purpose of removing the pharmaceutical product(s), thepush-through type foil lid of the blister pack lies against a coveringwall part with respect to which the blister pack can be displaced bysliding from a closed position, where the foil lid lies adjacent to asolid region of the covering wall part, to an open position in which theblister with the pharmaceutical product(s) lies in line with a tear-offstrip in the covering wall part, such that when the tear-off strip isremoved to create an opening in the covering wall part, thepharmaceutical product(s) can be pushed through the foil lid and theopening in the covering wall part.

[0014] Thus, the blister pack is preferably arranged between a rear wallpart, and a front part, and the covering wall part with the openings isan inner wall part lying between the rear wall part and the foil lid,whereby the blisters can be displaced by sliding from the closedposition to the open position into opening slits and the openings in theinner wall part are covered over by a tear-off strip which is arrangedin the rear wall part and can be separated from it along a line ofweakness thus forming a longitudinal slit.

[0015] The packaging according to the above-mentioned aspects of theinvention thus combines tear-off strips and a blister pack that can bedisplaced by sliding in the packaging as preferred elements that servethe purposes of child safety, and results in a packaging arrangementproviding greater child safety than conventional forms of packaging.

[0016] Opening the packaging according to the above-mentioned aspects ofthe invention requires combination skill that recognizes that, in orderto push the pharmaceutical product(s) out, the blister pack has to bemoved to a particular position and also that it is necessary to remove atear-off strip from a wall part of the packaging.

[0017] The wall parts of the packaging may consist of cardboard or aplastic material, e.g. PVC (polyvinyl chloride). The wall parts may besingle-layer or multi-layer parts, where the latter parts may contain acombination of cardboard and plastic materials.

[0018] The opening slits may be arranged perpendicular to the tear-offstrips. In this case the displacement of the blister pack isperpendicular to the direction of the tear-off strip. In an embodimentwhere the package contains an inner wall part, the opening slits mayalso run parallel to and over the tear-off strips. In this case thedisplacement of the blister pack is in the longitudinal direction of thetear-off strips.

[0019] The front part and the inner wall part are preferably joined bymeans of e.g. gluing or hot sealing at their peripheries at least inpart and such that the blister pack lying in between can be displaced bysliding in the longitudinal direction of the opening slit. The rear wallpart and the inner wall part are preferably at least in part or all-overjoined by means of e.g. gluing or hot sealing in the region surroundingthe tear-off strip, so that children are not able to tear off the rearwall from the inner wall when the tear-off strip is torn off.

[0020] An additional layer can be attached to the front part on its sidefacing the blister pack. The additional layer can be provided at leastin part, i.e. in the region of the opening slits, or all-over. Furtheran additional layer can be attached to the rear wall part on its sidefacing the blister pack. The additional layer can be provided at leastin part, i.e. in the region surrounding the tear-off strips, orall-over. The additional layers are e.g. made of a plastic material,preferably of PVC, and they can e.g. be glued, heat sealed or laminated.The additional layers serves to prevent tearing the front part withrespect to the rear wall part.

[0021] In order to increase child safety further the resistance tosliding displacement of the blister can be increased in that the openingslits exhibit narrow regions, breakable barriers or other suitable meansbetween the closed position and the open position. The greaterfrictional resistance to the blister at the narrow regions in theopening slits has to be overcome by stronger pressure applied by thefingers. Further the opening slit may be closed with a tear-off strip,whereby the tear-off strip is joined to the front part e.g. by a line ofweakness, preferably a line of perforations. By tearing off the strip,the opening slit is freed an the blister is movable.

[0022] The arrangement of the inner wall part offers the advantage that,after removing the tear-off strip the foil lid of the blister pack isstill not visible. In order that the openings in the inner wall part arealso not readily visible, these can be covered by an opening closurethat can be pushed through. The opening closure can be a defined area ofthe inner wall part which is delimited by a closed line of weakness,e.g. a notched or stamped line.

[0023] Further, it has also been found advantageous to cover the innerwall part on its side facing the rear wall part and/or on its sidefacing the foil lid with a protective layer of plastic material. Theplastic material is preferably a PVC-layer. The protective layer can belaminated, heat sealed or glued onto the inner wall part. As a resultthis removes the possibility of small children in particular exposingthe prepared openings after removal of the tear-off strips and possiblyother rear wall parts.

[0024] According to a further aspect of the invention there is provideda child-proof package for tablets and similar pharmaceutical products,comprising a blister pack with at least one blister which is closed offby a push-through type foil lid, the blister serving the purpose ofaccommodating the pharmaceutical product(s), the packaging being suchthat the push-through type foil lid of the blister pack lies against acovering wall part, whereby the covering wall part is a multi-layer partand contains an inner layer facing the foil lid of the blister and anouter layer. The outer layer may be bonded to the inner layer in part orall-over. The inner layer contains an opening covered by a push-throughopening closure which is delimited by line of weakness. The openingclosure lies for the purpose of removing the pharmaceutical product overthe blister. The outer layer contains an opening which lies on theopening closure. The said opening is preferably a hatch-like opening.The opening and the opening closures are preferably circular and theopening is preferably concentrically arranged on the opening closure.The opening of the outer layer is preferably equal or smaller than theopening closure. That is to say, the diameter of the opening of theouter layer is preferably equal or smaller than the diameter of theopening closure. The outer layer features an annular region surroundingthe opening. The annular region of the outer layer is not bonded to theinner layer. The annular region is delimited towards the plane outerlayer by means of a line of weakness, e.g. a circular line ofperforations. The annular region preferably contains radial lines ofweakness, e.g. cuts or lines of perforations, which subdivide theannular region into sectors. If the opening is smaller than the openingclosure then the line of weakness of the opening closure is protectedunder the annular region and on pressing out the pharmaceutical product,the individual sectors stick out in the shape of a crown or a bloom. Theinner layer is preferably made of cardboard and the outer layer ispreferably made of a plastic material, e.g. PVC.

[0025] The described annular region represents a mean for diversion ofattention of the children, which first try to open the packaging bydetaching the loosened annular region, particularly the loosenedsectors, from the laminate. This way children hardly pay attention tothe underlying opening closure.

[0026] A rear wall part may be arranged adjacent to the outer layerfacing of the covering wall part, whereby the opening of the coveringwall part is covered over by a tear-off strip which is arranged in therear wall part and can be separated from it along a line of weaknessthereby forming a longitudinal slit.

[0027] A further contribution to increasing child safety in thepackaging according to the invention can be made by special shaping ofthe tear-off strip. This exhibits preferably a gripping flange thatterminates in an edge part of the rear wall part, that is freed from itonly after bending the edge part, and can then be gripped between twofingers. The gripping flange can be delimited from the edge part bymeans of a cut or line of weakness, e.g. a punched line or a line ofperforations, so that after bending the edge part the gripping flange isfreed along the line of weakness and sticks out of the edge part.

[0028] As a further contribution to increasing child safety in thepackaging, means, e.g. spring-loaded elements, can be provided whichautomatically set back the unhanded blister pack from the opened to theclosed position by displacing in the opening slit.

[0029] The package according the invention can contain one or more cupswhich are movable individual or together in groups. The cups of ablister pack containing a number of cups may e.g. be arranged andmovable in rows or in columns. In this case the cups may be movablehorizontal or vertical with regard to the rows and columns of cups. Inthe embodiment where the movement of the cups is perpendicular to a rowor a column of cups the displacement of the row or column is preferablyonly successful by pushing at least two cups at once. The slidingdisplacement by pushing e.g. only one single cup of a row or columnaffects that the blister pack tilts in a diagonal position in such amanner that at maximum one cup of the row or column does move into linewith the openings in the adjacent wall.

[0030] The packaging according the invention can be developed in theform of a single card containing at least one blister pack with at leastone cup, where the cups are arranged in rows and columns. Further thepackaging may be developed in the form of a foldable strip shaped cardwith several segments that can be folded, where the segments may containblister packs as forgoing described.

[0031] A useful design of the packaging according to the inventioncomprises of a strip-shaped card which can be folded together, wherebyin the folded state one end part is folded over a first folding axisonto a middle part and is covered by a lid part folded over a secondfolding axis. A blister pack is preferably provided in both the middlepart and in the end part, whereby the blister pack in the middlecontains a daily dose e.g. of a first kind of table or similarpharmaceutical product intended to be taken in the morning and theblister pack in the end part contains the daily dose of a second kind oftablet or similar pharmaceutical product to be taken in the evening.

[0032] In a first version of the packaging according to the inventionthe opening slits may be arranged perpendicular to the tear-off strips.In a second version, the opening slits are arranged parallel to and overthe tear-off strips.

[0033] The line of weakness in the wall part to delimit the tear-offstrip is preferably a line of perforations.

DETAILED DESCRIPTION OF THE INVENTION

[0043] A package 10 for tablets 12 or similar pharmaceutical products(e.g. liquid-filled or solids-filled capsules, etc.) is shown in FIGS. 1and 2. The package 10 has the form of a flat elongated rectangular(strip-shaped) card with parts that can be folded together, whereby, inthe folded state, one part C is folded along a first folding axis f ontoa middle part B and is covered by a lid part A folded along a secondfolding axis e. The size of the package 10 folded together in thismanner is about one third of the unfolded strip-shaped card. The cardcontains rear wall parts 14B, 14C and front wall parts 16B, 16C.

[0044] Situated between the rear wall parts 14B and 14C of the middlepart B or the end part C and the corresponding front parts 16B and 16Care, in each case, blister packs 18B, 18C. The blister packs 18B, 18Ccomprise a blister film 20, made for example of PVC, in which blistersor cups 22 are provided, e.g. by thermoforming. The open side of theblister 22 is closed off by a foil lid 24 made, for example, of aluminumfoil, through which the contents can be pressed.

[0045] In the illustrated embodiment, the middle part B has seven rowsof blisters 22, each for three tablets running in a first horizontaldirection x, and the end part C has seven rows of blisters 22 each fortwo tablets running in a first horizontal direction x. Each blister pack18B, 18C comprises a row of blisters 22. The tablets in the middle partB are, for example, intended to be taken in the morning and those in theend part C to be taken in the evening. The seven rows of tabletscorrespond to the seven days in the week. The version of packaging 10shown here corresponds therefore to a weekly pack for consumption of twoor three tablets twice daily.

[0046] Integrated into each of the rear wall parts 14B, 14C of themiddle part B and end part C are seven tear-off strips 26 running in thefirst, horizontal direction x. The front parts 16B, 16C of the middlepart B and end part C exhibit—corresponding to the blister packs 18B,18C—three or two opening slits 44 running in a second perpendiculardirection y. The blisters 22 are introduced from the rear side of thefront part 16B into these opening slits 44 in the longitudinal directionof the opening slits 44—the largest opening width b of which slits 44corresponds basically to the diameter of an individual blister 22 in theblister packs 18B, 18C. The front parts 16B, 16C and the rear wall parts14D, 14C are joined at their peripheries at least in part and such thatthe blister packs 18B, 18C lying in between and delimited by itsperiphery 19 are enclosed in the middle part B and end part C and can bedisplaced by sliding only in the longitudinal direction y of the openingslit 44. As a result of this limited ability of displacing the blisterpacks 18B, 18C each row of tablets has two extreme positions—namely, aclosed position S and an open position O. The displacement t betweenboth extreme positions of the blister packs 18B, 18C is a result of thelimited possibility to displace the blister packs inside the middle partB and end part C or as a result of the corresponding selected length ofopening slit 44. The opening slits 44 are selected such that there ispreferably a narrowing 45 between the closed position S and the openposition O. As a consequence of this narrowing 45, a frictional force ofresistance has to be overcome on displacing the blister 22 from theclosed position S to the open position O. This feature, i.e. thenarrowing 45 of the opening slit 44, results in a significant increasein the child-proof property of the package 10. It is clear that afterremoving a dosage of tablets 12 the blister packs 18B, 18C must bepushed back into the closed position S to keep the packaging 10child-proof.

[0047] In the example shown here, the pairs of blisters 22 in the endpart C of the blister packs 18C are in each case displaced a horizontaldistance from each other. In this case, of course, the opening slits inthe front part 16C are corresponding in shape and feature regions 44 a,44 b which are displaced with respect to each other.

[0048] In the open position O, the tablets 12 are situated in a row—asviewed in their projection onto the plane of the drawing—over thetear-off strip 26 or over a longitudinal slit 27 in the rear wall parts14B, 14C defined by it.

[0049] As shown in FIG. 3, an inner wall 36 is provided on the innerside of the rear wall part 14B, which is made e.g. of cardboard. Thisinner wall part 36, which is likewise made of cardboard, is preferablyprovided with a protective layer or film 42 e.g. of PVC(polyvinylchloride) on its side facing rear wall part 14B.

[0050] Provided in the inner wall part 36, by means of notches orpartially stamping through the inner wall part 36, are openings 38 whichin the unopened package are closed off e.g. by the stamped parts 40. Thenumber and arrangement of the openings 38 corresponds to the number andarrangement of the individual blisters 22 in the blister pack 18B. Asviewed in their vertical projection to the plane of the middle part Bthe openings 38 lie within the corresponding opening slits 44 in thefront parts 16B, 16C. The diameter m of the openings 38 is chosen tocorrespond to the diameter of the tablets 12 in such a manner that thetablets can be pushed through the openings without any great effort.

[0051] The opening of the packaging 10 and the removal of the requireddaily dose of tablets 12 is described in the following with the aid ofFIGS. 4 to 6.

[0052] In order to make the tear-off strips 26 in the middle part Baccessible, first the cover part A has to be opened from the middle partB. Starting from the edge at the side of the middle part B are cuts 30which run in the first horizontal direction x parallel to the tear-offstrips 26 and form between them edge parts 32 which extend up to afolding line p. Via a line of weakness or perforations 28 along thewhole length up to the folding line p, the tear-off strips 26 arereleasably attached to the rear wall part 14B. A part of the tear-offstrip 26 extending into the edge part 32 is designed as a flange 34 forgripping the tear-off strip 26: whereby in order to form the edge regiondelimiting the gripping flange 34, the line of weakness 28 of thetear-off strip 26 is punched through in the edge part 32. As a result,on bending back the gripping flange 34 is freed from the edge part 32,i.e. the flange for gripping 34 remains and can be readily grippedbetween two fingers and the tear-off strip 26 removed from the rest ofthe back wall panel 14B.

[0053] The procedure described for middle part B, i.e. for removing atear-off strip 26, also applies analogously to end part C, whereby inthat case the cuts 30 and therefore the prepared edge parts 32 in rearwall part 14C are already lying free.

[0054] After the tear-off strip 26 has been removed from the appropriaterear wall part 14B, 14C for the desired time of day and desired day, theblisters 22 are pushed out of their closed position S by thedisplacement distance t into the open position O. This displacementtakes place at the front side 16B, 16C in such a manner that two fingersengage the blisters lying farthest apart and the blister pack 18B, 18Cis pushed parallel to the opening slits 44 by applying pressuresimultaneously by both fingers.

[0055] If an attempt is made to effect the sliding displacement e.g. bypushing only one single blister 22, the blister pack 18B, 18C tilts in adiagonal position in such a manner that the whole row of tablets doesnot move into line with the tear-off strip 26. As a result, at most onlyone tablet can be pressed out of the pack, thus providing increasedchild safety as small children are hardly able to achieve the requiredparallel displacement of the blister pack 18B, 18C. In addition to therequired parallel displacement of the blister pack 18B, 18C there is thefurther hindrance in that the narrowing of the opening slits 44 createsresistance to displacement so that the displacement movement which isabsolutely necessary to be able to remove the tablets 12 can not beachieved by a small child.

[0056] After the desired tear-off strip 26 has been removed and theblister has been brought into the open position O, the tablets can bepressed out of the selected row of individual blisters 22, through theprepared openings 38 and out of the package 10. In the example shown inFIG. 3 the inner wall part 36 is of cardboard optionally laminated,glued or heat sealed with a PVC film acting as a protective layer 42.This results in increased child safety in that after removing one ormore tear-off strips 26 or the whole rear wall part 14B, 14C, thepre-stamped or notched openings 38 in the inner wall part 36 are notreadily accessible for a small child. The PVC layer prevents smallchildren from being able to free or scratch out the prepared openings38. Furthermore, the PVC coating makes it necessary to apply additionalforce to press out the tablets. Of course, other shapes of preparedopenings 38 are possible. It is possible for example to prepare theopening by means of a star-shaped cut forming essentially triangularsegments, whereby on pressing out the tablet, the individual segmentsopen in the shape of a spiky crown. Likewise, the PVC film, which isused as a protective layer 42, may exhibit a line of weakness thatcorresponds to the opening formed later.

[0057] The rear wall part 14B, 14C may be joined to the underlying innerwall 36 or the protective layer 42 on it, in such a manner that thetear-off strip 26 separates from the underlying wall part 36 orprotective layer 42 by peeling.

[0058] In the example shown the front parts 16B, 16C are of cardboard asare the rear wall parts 14B, 14C. In order to increase the resistance ofthe rear wall parts 14A, 14B, 14C and front parts 16B, 16C to tearing, alaminate containing plastic e.g. a cardboard/PVC laminate may beemployed.

[0059] In the example shown, the opening slits 44 are arrangedperpendicular to the tear-off strips 26. It is self-evident that theopening slits 44 may also run parallel to the tear-off slits 26. In thiscase the displacement of the blister packs 18B, 18C is in thelongitudinal direction of the tear-off strips 26. This does not,however, change anything with respect to the basic principle of theorientation of the individual blisters 22 or tablets 12 withcorresponding openings 38.

[0060] In an embodiment that is slightly different from that of FIG. 1,the blisters of the blister packs are arranged in columns (not shown inthe drawings). The opening slits may be vertically arranged, i.e. theblister packs are vertically displaced, according FIG. 2, whereby notilting of the columns of the blister packs will occur by pushing onlyone single blister. The opening slits may also be horizontally arranged,i.e. the moving of the blister packs is horizontally, whereby a tiltingof the columns of the blister packs will occur by pushing only onesingle blister as above described.

[0061]FIG. 7a, FIG. 7b show an embodiment of the covering wall partaccording to a further aspect of the invention. The covering wall partis a multi-layer part 50 which contains an inner layer 56 facing thefoil lid of the blister and an outer layer 55, which may facing a rearwall part. The inner layer 56 contains a circular push-through openingclosure 53 which is delimited by a line of perforations 54. The outerlayer contains a circular opening 57 which is concentrically arranged onthe opening closure 53, whereby the opening 57 is smaller than theopening closure 53. The outer layer 55 features an annular region 61which surrounds the opening 57 and which is not bonded to the innerlayer 56. The annular region 61 is delimited towards the plane outerlayer 55 by means of a line of perforations 51. The annular region 61preferably contains radial cuts 60, which subdivide the annular region61 into sectors 52. On pressing out the pharmaceutical product, theopening closure 53 is pushed out and the individual sectors 52 open inthe shape of a crown.

A child-proof package for pharmaceuticalproduct(s), comprising a blister pack with at least one blister which isclosed off by a push-through type foil lid, the blister serving thepurpose of accommodating the pharmaceutical product(s), the packagingbeing such that, for the purpose of removing the pharmaceuticalproduct(s), the push-through type foil lid of the blister pack liesagainst a covering wall part with respect to which the blister pack canbe displaced by sliding from a closed position, where the foil lid liesadjacent to a solid region of the covering wall part, to an openposition in which the blister with the pharmaceutical product(s) lies inline with a tear-off strip in the covering wall part, such that when thetear-off strip is removed to create an opening in the covering wallpart, the pharmaceutical product(s) can be pushed through the foil lidand the opening in the covering wall part.
 13. The package of claim 12,wherein the blister pack is arranged between the covering wall part anda front part, whereby said at least one blister can be displaced bysliding from the closed position to the open position into opening slitsin the front wall part, and wherein the opening slits exhibit narrowregions between the closed position and the open position in order toincrease the resistance to displacing the blister by a sliding action.14. The package of claim 12, wherein the tear-off strip exhibits agripping flange that terminates in an edge part of the rear wall partand on bending the edge part is freed from it and sticks out of the edgepart, and can be gripped by two fingers.
 15. The package of claim 12,wherein the opening slits are arranged perpendicular to the tear-offstrips.
 16. The package of claim 12, wherein the line of weaknessprovided in the rear wall part to delimit the tear-off strip is a lineof perforations.
 17. A child-proof package for pharmaceuticalproduct(s), comprising a blister pack with at least one blister which isclosed off by a push-through type foil lid, said blister serving thepurpose of accommodating the pharmaceutical product(s), the packagingbeing such that the push-through type foil lid of the blister pack liesagainst a covering wall part, wherein the covering wall part is amulti-layer part containing an inner layer facing the foil lid and anouter layer, the inner layer having an opening covered by an openingclosure which can be pushed through and the outer layer having anopening which lies on the opening closure and which is surrounded by anannular region, whereby the annular region is not bonded to the innerlayer.
 18. The package of claim 17, wherein the opening of the outerlayer is smaller then the opening closure.
 19. The package of claim 17,wherein the annular region is subdivided in sectors which are not bondedto the inner layer and which stick out of the inner wall part in theshape of a crown when the opening closure is pushed through.
 20. Thepackage of claim 17, wherein a rear wall part is arranged adjacent tothe outer layer and facing the covering wall part, whereby the openingof the covering wall part is covered over by a tear-off strip which isarranged in the rear wall part and can be separated from it along a lineof weakness thereby forming a longitudinal slit.
